Our research

LTL tackles the most challenging problems in the field of low temperature research and nanophysics. This forefront position has been appreciated with the Center of Excellence (CoE) -status of the Academy of Finland ever since the beginning of the CoE-program in 1995.

Low Temperature Laboratory

The Low Temperature Laboratory, founded in 1965 by Academician Olli V. Lounasmaa, is one of the world centres in ultra low temperature physics and technology. The leading position is based on vigorous in-house development and construction of sub-mK refrigerators.

In 2000 the laboratory reached the present low temperature world record of 0.000 000 000 1 K. Scientific and technical staff of LTL has in-depth expertise in cryogenic techniques, development of cryogenic equipment and thermal control systems. Most of the LTL unique cryogenic equipment, including dilution refrigerators, were designed in the LTL and manufactured in the laboratory workshop.

LTL has advanced sub Kelvin refrigeration facilities: two sub-mK (unique rotating cryostat and world record stationary cryostat) and more than 10 dilution refrigerators aimed for different type of experiments.
